Copyright (C2010-2013) Yang XIAO, BJTU, April 16, 2010, E-Mail: yxiao@bjtu.edu.cn. This program can produce the Parity Check Matrices of DVBS2 codes, while Ref. [1] remindes you that these codes are not good as the LDPC codes IEEE802.16e for continuous bits' errors. Refenrences: [1] X. Huang, Y....

These codes were used in preparation of manuscript Korhonen, L. & Heikkinen, J. 2009. Automated analysis of in situ canopy images for the estimation of forest canopy cover, Forest Science 55(4): 323-334. The codes can be used to threshold skyward-looking canopy images with a edge-detection based...

I found the Data Acquisition Toolbox too slow for my needs in sending 16-bit digital codes with my PCIM-DAS1602, so I adapted C code from the MCC Universal Library to send codes very fast, at up to 10kHz. This code simply sends two bytes, and then flips a strobe on and off. You can send character...

The program constructs girth-6 type III qc-ldpc codes given base matrix and sub-matrix size. The sub-matrices sizes are variable. The program uses a search algorithm. It could fail to construct a code given some parameters. In that case the user could try many times or could simply increase the...

We found that the generator matrix in Fig.6-2 to be wrong, Bi,j's are not circulant. You can not derive circulant Bi,j's from the parity check matrix in Fig.6-1.There are two vital problems in the LDPC codes of CCSDS 131.0-P-1.1: (1) the parity check matrix in Fig.6-1 is not full rank; (2) the...
